I HOT-AIR BATH.

Application filed December 27, 1924.

This invention refers broadly to hot air baths or devices for thetreatment of the human body with hot air or similar fluids, and itrefers in particular to devices of this kind adapted for the treatmentof the head, and it is one of the important objects of this invention toproduce a very thorough circulation of the air which is heated by anysuitable heating means provided in the interior thereof, suchcirculation being etfected by an electric tan or the like which islikewise mounted in the frame or casing of the apparatus; and in furtherpursuance ot my invention I provide means of directing the heated air orthe like upon the head of the person to be treated by the aid oi":preterably hood shaped means or cowl forming a part of the apparatus.

The invention will be more fully described with reference to theaccompanying drawing, showing by way of example an embodiment of theinvention in elevation.

The apparatus comprises a capsule or casing 2 mounted on a suitablesuspension device 1, and provided at its bottom portion with anexchangeable extension or annulus 3 carrying a piece of cloth or fabricwhich may be tied or otherwise arranged so as to constitute a hood orkind of cowl, and which is provided with one or more venting apertures 5for the escape of the air. In the easing or capsule a fan or ventilator8 operated by electric means, for instance by an electric motor 7, and,for instance, two heating bodies 9 are arranged. The nature and shape ofthese heating bodies may be of any desired description. Instead of twoheating bodies I may, for instance, employ only one heating body. F orthe purpose of regulation or the heat electric means may be providedwhich may be manipulated by means of a cord or by an electric conduit 6secured thereto and extending to the outside. By this means the heatingof the device may be controlled and regulated in any desired manner bythe person undergoing the heat treatment or may be entirely dispensedwith. The cloth 4 may be made of any desired material, such as, forinstance, wool, silk, rubber and the like.

The apparatus may be suspended from the ceiling, as shown in thedrawing; or it Serial No. 758,445.

may be mounted 011 a bracket and suspended from a suitable support, orfrom a holder, hook or the like, or mounted in any other convenientmanner.

The mode of operation of the device is substantially as follows Uponoperating the tan or ventilator it will induce a current of air into theinterior of the apparatus, the air being heated by the electricresistance. Inasmuch as the substantially hood-shaped casing 2 is closedat one end, the air can only enter through the apertures 5 and iscirculated within the en closures 2 and l by the vanes 8 and is therebydirected onto the part to be treated which is thus thoroughly bathedwith the heated air. The amount of heat and the capacity of the heatingresistance may be regulated by a press button or the like connected tothe resistance or the conductor 6 to suit the person to be treated.Inasmuch as the hood is closed to the outside the hot air can only actupon the head or other parts of the body of the person, and can onlyescape through the venting apertures 5. The new device is, therefore,easily manipulated by the patient himself and produces a thorough andeiiicient treatment of the hair or the body of the patient. Theapparatus may also be employed for the purpose of drying the hair afterwashing the same, for the treatment of the head with hot fluids, forhead shower-baths,

for head sweat baths and for similar kinds of treatment; and it shouldbe understood that the invention is not limited in every respect to theexact particulars and construction and arrangements of parts, sincemodifications and changes may occur to suit the needs and convenience ofthe operator and of the patient, and without deviating from the spiritand scope of the invention as set forth in the appended claims. Theinvention is, moreover, obviously not limited to the use of air as atreating fluid.

I claim 1-- 1. In a device of the character described, a substantiallyhood-shaped casing closed at one end,'electric heating means within thecasing and air-circulating means asso ciated therewith, an extension offlexible material at the open end otsaid casing adapted to envelop thepart to be treated, an aper tured portion in the Wall of said extensionand controlling means for the heating and air-circulating means.

2. In a device of the character described, a casing With one end closed,an electrically operated fan and electric heating means in the casing, ahood of flexible material at the open end of the casing, adapted toenvelop the part to be treated, an apertured portion in the Wall of thehood, and 21- depending fleX- l ible electric conduit at the side o1 thehood and connected to the heating means.
